Hey Tracy we are the minority here, mine is in my 1968 SWB I purchased a harness from Painless it was a nice standalone harness, I will modify my original one sometime for my next conversion but I was in a bit of a time constraint this time. My original motor plans for my truck didnt work out so well.
I did get Allen at Nelson performance to tune mine after that.

So welcome and would love to see some pictures of the truck and install. I can post some of mine too. It sure makes this "old" truck fun to drive.
